org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x7)

我想用replaceAll("[\\r\\n]",",")把空白方框乱码替换掉，匹配不到这个字符，怎么匹配到这个字符？

 

java.util.regex.Pattern INVALID_XML_CHARS = Pattern.compile("[^\\u0009\\u000A\\u000D\\u0020-\\uD7FF\\uE000-\\uFFFD\uD800\uDC00-\uDBFF\uDFFF]");

x_contact_method = INVALID_XML_CHARS.matcher(x_contact_method).replaceAll(" ");
